    "abstract": "The scales of the Standard Model correspond to the positions of domain wall\nintersections on a straight line in a noncompact two-dimensional extra space.\nThe domain walls partition an Anti-de Sitter spacetime. We show that domain\nwall intersections mark the orthogonal intersections of 1-cycles winding around\na rectangular compact space and a hierarchy of subspaces, and that the\nnoncompact extra space of the model is a covering space. 4-branes wrap 1-cycles\nof the compact spaces and intersect orthogonally in 3-branes, upon which the\nparticles propagate. We show that particles are located precisely at domain\nwall intersections in the covering space.",
